.................60's & 70's muscle cars are very popular with the middle-aged crowd. More so every year for awhile now. And then there's the old farts who spend $20k for a Harley and never even figure out how to set the timing or change the oil. The ACVW enthusiasts are a vanishing breed it seems with fewer and fewer vendors selling to fewer and fewer owners every year. The fact that it's only a rewarding hobby for those who are willing to work on them is a big hurdle for most people nowadays. It hasn't been a dramatic decline in any of the last several years but is slowly and steadily happening. I'd say that there isn't very much appeal for them with the teenagers and twenty somethings either who are usually more interested in driving a re-chipped Civic with a ground effects kit and coffee can sticking out the back end. I don't care too much about the popularity thing as long as I can keep driving mine but it will have a bad effect on the price and availability of parts, eventually.
BTW.............I've been here for six going on seven years and I remember your name but that's about all. Are you going to stick around this time..........lol
